How to simulate and determine whether methane is in a supercritical state under certain conditions?
It can be determined using a pressure-enthalpy diagram.
If using HYSYS, it is possible to view the physical properties of that component, as well as its critical temperature and pressure, and to examine phase diagrams
I think for this issue—the supercritical state of methane—there’s no need to conduct simulations. Perhaps the original poster wants to know how to find information about other substances? In the book \"Physical Chemistry\" written by Chahua Li and Hu Ying, the critical temperature of methane is 190.7 K. The book defines a supercritical fluid as a fluid whose temperature and pressure are slightly above its critical values. For methane, if the temperature is too high, isn’t it no longer in a supercritical state? Like room temperature?
